Recommendation 32

Blue hydrogen may have value as a transitional measure which builds a market for hydrogen and provides supply over the shorter term. However, excess reliance on blue hydrogen could leave the UK exposed to volatile international gas prices and risk increasing greenhouse gas emissions due to the threat of methane leakage. In response to this report, we ask that the Government sets out how its plans for blue hydrogen will address recent evidence that hydrogen emissions escaping from gas pipelines have a stronger warming effect in the atmosphere than previously thought. It should include in that response an account of how it will ensure that efforts to constrain and monitor methane leakage at point of extraction, transportation and storage are robust.
